Abstract

The invention discloses an inorganic powder for inhibiting sulfate-reducing bacteria by using tourmaline-loaded manganese and a preparation method thereof, which relates to a bacteriostatic agent and a preparation method thereof. It solves the problems of poor safety, poor heat resistance, easy decomposition and short service life of existing organic antibacterial agents. The invention is made of 60-99.99% of tourmaline and 0.01-40% of potassium permanganate solid or manganese chloride solid or the mixture of potassium permanganate solid and manganese chloride solid according to mass percentage. The preparation method is: use nanometer or submicron tourmaline to stir in deionized water; add nitrate solution; add potassium permanganate solid or manganese chloride solid or a mixture of potassium permanganate solid and manganese chloride solid and a dispersant , stirring; decompression suction filtration separation, cleaning with deionized water; drying the powder; grinding and calcining the powder and grinding the powder again to obtain an inorganic antibacterial powder. The invention not only effectively increases the amount of manganese loaded, but also improves the bactericidal effect of the bacteriostatic agent.

Description

technical field [0001] The invention relates to the technical field of antibacterial powder and its preparation, in particular to natural tourmaline-loaded manganese inorganic antibacterial powder and a preparation method thereof. Background technique [0002] In recent years, with the accelerated development of the national economy, the pollution of industrial wastewater, especially sulfate wastewater, has been quite serious. The groundwater of many large cities in my country has been polluted by sulfates to varying degrees. Discharge of sulfate-containing acidic wastewater directly into the water body without treatment will acidify the receiving water body, reduce the pH value of the water body, endanger aquatic organisms, and cause potential corrosion; this type of acidic wastewater will also damage the soil structure and reduce crop yields. Sulfate wastewater has a long incubation period, and although it has the activity of natural reducing bacteria, it has become a ver...
